May 15 09:20:10 chef hydra-queue-runner[27523]: Hydra::Plugin::GitlabStatus=HASH(0x519a7b8)->buildFinished: Can't call method "value" on an undefined value at /nix/store/858hinflxcl2jd12wv1r3a8j11ybsf6w-hydra-0.1.2629.89fa829/libexec/hydra/lib/Hydra/Plugin/GitlabStatus.pm line 57.
No more need for a reproduction script! It just says something like
If you have Nix installed, you can reproduce this build on your own
machine by running the following command:
# nix build github:edolstra/dwarffs/09c823e977946668b63ad6c88ed358b48220f124:hydraJobs.build.x86_64-linux
This plugin expects as inputs to a jobset the following:
- gitlab_status_repo => Name of the repository input pointing to that
status updates should be POST'ed, i.e. the jobset has a git input
"nixexprs": "https://gitlab.example.com/project/nixexprs", in which
case "gitlab_status_repo" would be "nixexprs".
- gitlab_project_id => ID of the project in Gitlab, i.e. in the above
case the ID in gitlab of "nixexprs"
The hydra-queue-runner opens a connection to the builder. If the
builder is 'localhost' it starts `nix-store`, otherwise it starts
'ssh'.
Currently, if the hydra-queue-runner can not start `nix-store` (not in
the PATH for instance), the error message is:
cannot connect to ‘localhost’: error: cannot start ssh: No such file
or directory
This is not useful since ssh is actually not started:/
With this patch the error message is now:
cannot connect to ‘localhost’: error: cannot start nix-store: No such file
or directory
Some time ago the data structure for maintainer descriptions in
`nixpkgs` changed from a simple attr set with maintainer emails as
values to an attribute set where the maintainer' nick is associated to
an attribute set with email, GitHub handle and full name.
Hydra can either parse a Nix list or fetches `shortName` from the
associated attribute set (which is used for `meta.licenses` as each
value in it contains a `shortName`). This behavior needs to be
replicated for maintainers to retrieve the emails for `hydra-notify`.
This change is backwards-compatible since `queryMetaStrings` is still
able to understand lists, so old versions of `nixpkgs` or packages using
the old maintainer data structure remain usable.
This is because setting only the initial heap size to more than
the default value (or the configured value) will cause all initial evals
until maxHeapSize expands to the given value to abort.
The 1.1 multiplier comes from the the configured defaults on NixOS' hydra,
and from the previous multiplier used before
7876cf677c.
In order to access protected or private repositories. Using the target
repository URL along with the merge-request ref instead of the source
repository url and branch is necessary to avoid running into issues if
the source repository is not actually accessible to the user Hydra is
authenticating as.
Thanks Alexei Robyn for this patch.
